This series adds ethernet support for the StarFive JH7110 RISC-V SoC. The series includes MAC driver. The MAC version is dwmac-5.20 (from Synopsys DesignWare). For more information and support, you can visit RVspace wiki[1]. You can simply review or test the patches at the link [2]. This patchset should be applied after the patchset [3], [4], [5].

Patch 12: - No update Patch 11: - Configuration of gmac and phy for visionfive 2 v1.2A. Patch 10: - Configuration of gmac and phy for visionfive 2 v1.3B. Patch 9: - Added starfive,syscon for gmac nodes in jh7110.dtsi. Patch 8: - Added starfive_dwmac_set_mode to set PHY interface mode. Patch 7: - Added starfive,syscon item in StarFive-dwmac dt-bindings. Patch 6: - Moved SOC_STARFIVE to ARCH_STARFIVE in Kconfig. - Dropped the _PLAT/_plat from the config/function/struct names. (by Emil) - Added MODULE_DEVICE_TABLE() and udev will load the module automatically. (by Emil) - Used { /* sentinel */ } for the last entry of starfive_eth_match. (by Emil) - Added 'tx_use_rgmii_rxin_clk' to struct starfive_dwmac, to mark the clk_tx'parent is rgmii. - Suggested by Emil, dropped clk_gtxclk and use clk_tx_inv to set the clock frequency. Patch 5: - Suggested by Emil, dropped mdio0/1 labels because there is no reference elsewhere. Patch 4: - Removed GTXC clk in StarFive-dwmac dt-bindings. - Added starfive,tx-use-rgmii-clk item in StarFive-dwmac dt-bindings. Patch 3: - Added an optional reset single 'ahb' in 'snps,dwmac.yaml', according to stmmac_probe_config_dt/stmmac_dvr_probe. Patch 2: - No update Patch 1: - No update Changes since v3: - Reworded the maxitems number of resets property in 'snps,dwmac.yaml' - Removed the unused code in 'dwmac-starfive-plat.c'. - Reworded the return statement in 'starfive_eth_plat_fix_mac_speed' function. Changes since v2: - Renamed the dt-bindings 'starfive,jh71x0-dwmac.yaml' to 'starfive,jh7110-dwmac.yaml'. - Reworded the commit messages. - Reworded the example context in the dt-binding 'starfive,jh7110-dwmac.yaml'. - Removed "starfive,jh7100-dwmac" compatible string and special initialization of jh7100. - Removed the parts of YT8531,so dropped patch 5 and 6. - Reworded the maxitems number of resets property in 'snps,dwmac.yaml'. Changes since v1: - Recovered the author of the 1st and 3rd patches back to Emil Renner Berthing. - Added a new patch to update maxitems number of resets property in 'snps,dwmac.yaml'. - Fixed the check errors reported by "make dt_binding_check". - Renamed the dt-binding 'starfive,dwmac-plat.yaml' to 'starfive,jh71x0-dwmac.yaml'. - Updated the example context in the dt-binding 'starfive,jh71x0-dwmac.yaml'. - Added new dt-binding 'motorcomm,yt8531.yaml' to describe details of phy clock delay configuration parameters. - Added more comments for PHY driver setting. For more details, see 'motorcomm,yt8531.yaml'. - Moved mdio device tree node from 'jh7110-starfive-visionfive-v2.dts' to 'jh7110.dtsi'. - Re-worded the commit message of several patches. - Renamed all the functions with starfive_eth_plat prefix in 'dwmac-starfive-plat.c'. - Added "starfive,jh7100-dwmac" compatible string and special init to support JH7100.
